|Length:||15.7 mi (25.3 km)|
|Existed:||1987 – present|

The route's entire length is a limited access freeway; linking NC 540 in Morrisville with the Research Triangle Park (RTP), Downtown Durham and Interstates 40 and 85. It is a fairly urbanized commuter-route and suffers from peak-traffic during conventional rush hours. Speed limits on the freeway range from 55 mph (89 km/h) to 65 mph (105 km/h).
Its northern terminus with Interstate 85 is a partial interchange, where northbound NC 147 merges onto southbound I-85 and vice-versa. Travelers wanting to go north on I-85 and vice-versa must utilize the nearby U.S. 15-501 freeway.
Though the highway is commonly known as "NC 147" or "147" throughout the state, the highway does have other known names it uses locally in areas.
- Buck Dean Expressway – official name of NC 147 within the city limits of Durham (approved: December 14, 1984).
- Durham Freeway – name given by NCDOT to NC 147 north of I-40 through Durham to its northern terminus at Interstate 85.
- East–West Expressway – original name of NC 147 within the city limits of Durham; it was renamed to Buck Dean Expressway.
- Triangle Expressway – official name of the toll section of NC 147, overlaps with Triangle Parkway.
- Triangle Parkway – name given by NCDOT to the section between NC 540 to I-40.
The Triangle Expressway is an all electronic toll collection (ETC) and camera enforced toll road. There are three gantry locations along NC 147, all located on entrance/exit ramps. Those that do not participate in the ETC program will receive a bill in the mail and will have 30 days from date on bill before additional fees and civil penalties are applied.

The Durham Freeway began with a 1962 bond referendum. The first section of the road, completed in 1970 around downtown Durham, was designated Interstate 40. The original section extended from Chapel Hill Street to Alston Avenue and resulted in the destruction of a portion of the Hayti neighborhood as part of urban renewal, though a DOT engineer said the neighborhood likely would have been torn down anyway. The road was later extended west to Erwin Road and southward to where it now meets the current I-40, but the decision was made for I-40 to bypass Durham. The section inside the city was renamed. The road's other names have included East-West Expressway and the I.L. "Buck" Dean Freeway.
In 1979, planners said many of the city's roads needed widening, and the decision was made to extend the freeway to I-85. The first section in 1982 disrupted the Crest Street neighborhood, but the N.C. DOT moved 181 houses instead of tearing them down, an action that resulted in a 1987 third-place Federal Highway Administration award for "historic preservation and cultural enhancement". Eventually, the problems that caused the original I-40 extension to I-85 to be delayed were overcome, and NC 147 was extended through the city. Work began in 1993, and the eastbound lanes opened May 21, 1997. The section connecting the road to I-85 opened July 31, 1998.
On September 6, 2011, the south termini at T.W. Alexander Drive (exit 4) was permanently closed to make way for NC 147's extension to NC 540 in Morrisville; this made I-40 the temporary southern termini for three months. On December 8, 2011, the southern extension was opened. Dubbed the Triangle Parkway, the 3.4-mile (5.5 km) stretch of road is also part of the Triangle Expressway.
There are two future projects involving NC 147. The first is the East End Connector (Currently in planning and environmental study). That project was set to start construction in 2010, but was delayed until after 2012. The second is the NC 147 extension to McCrimmon Parkway, in Morrisville, which is scheduled for Reprioritization.
